基于爆炸声源的远程水下目标定位方法

Remote localization method for underwater target based on explosive sound sources

  • 摘要:
      目的  随着潜艇隐蔽性和作战能力的不断提高,水面舰艇面临的水下挑战日益严峻。为加强对潜艇的全面感知和持久监视预警能力,对利用水下爆炸声作为发射声源的远程目标探测方法进行系统研究。
      方法  基于双基地声呐定位原理,给出水下目标的解算方法;根据声呐方程给出的能量关系,推导系统最大探测范围的数学模型,利用数值仿真分析目标定位误差的空间分布,以及爆炸声源不同投放距离的目标探测范围及其定位精度。
      结果  结果表明,基于爆炸声源的水下目标探测不能在全平面上扩大探测区域,但在基线延长线附近的一定开角范围内,可获得较大的探测优势。在此基础上,通过合理配置多枚爆炸声源,可增大对潜艇的警戒纵深。
      结论  可为航空应召反潜提供有效目标信息。

     

    Abstract:
      Objectives  With the continuous improvement of submarines' stealth property and combat capabilities, the underwater challenges faced by surface ships are increasingly becoming serious. To enhance the capabilities of overall scenario awareness, sustained surveillance and early warning of submarines, this paper systematically studies the long-range target detection method using underwater explosive sound sources as the emission source.
      Methods  Based on the principle of bistatic sonar localization, the solution equation of underwater targets is given. According to the energy relationship, the mathematical model of the maximum detectable range of the system is deduced. The spatial distribution of the target localization error is analyzed by numerical simulation, the target detection range and localization accuracy of explosive sound sources with different deploying distances are examined.
      Results  The results show that the detection of underwater target based on explosive sound sources cannot expand the detection range in the whole plane, but it can obtain greater detection advantages in a certain angle range near the baseline extension line. On this basis, by reasonably allocating multiple explosive sound sources, the warning distance of the submarine can be increased.
      Conclusions   Effective target information can be provided for aircraft-based on-called antisubmarine operation.
